Childhood disability in Aboriginal and Torres Strait Islander peoples: a literature review.

INTRODUCTION: Aboriginal and Torres Strait Islander children have higher rates of disability than non-Indigenous children and are considered doubly disadvantaged, yet there is very little data reflecting prevalence and service access to inform design and delivery of services. Failing to address physical, social, and psychological factors can have life-long consequences and perpetuate longstanding health disparities.
METHODS: A narrative literature review was undertaken to identify peer reviewed literature describing factors impacting on the prevention, recognition, and access to support and management of disability in Indigenous Australian children.
RESULTS: Twenty-seven peer-reviewed journal articles met inclusion criteria. The majority of articles focused on the hearing loss and learning disabilities consequent of otitis media. Few articles reported data on urban or metropolitan Indigenous populations or described interventions. Individual/community-, provider-, and systems level factors were identified as impacting on recognition and management of disability in young Indigenous children.
CONCLUSIONS: Given the burden of childhood disability, the limited literature retrieved is concerning as this is a barometer of activity and investment. Solutions addressing childhood disability will require collaboration between health, social and educational disciplines as well as an increased investment in prevention, identification and promotion of access.

Introduction

Early childhood is a critical period that can influence a range of health and social outcomes throughout the life course. In Australia, an economically prosperous and generally healthy nation, Aboriginal and Torres Strait Islander Peoples (hereafter, Indigenous) suffer worse health, disadvantage, and disability comparable to many developing nations [1]. Dispossession, disempowerment, and racism contribute to adverse outcomes [2,3]. Indigenous children with a disability are considered ‘doubly disadvantaged’, and failing to address physical, social and psychological factors can have life-long consequences [4,5]. High rates of childhood disability in Indigenous children fuel health inequities and should be an important focus of attention for policy makers and health professionals.

Disability in Indigenous Australians

For the purposes of this paper, the term disability refers to the long-term physical, mental, intellectual, or sensory impairments that hinder full and effective participation in society on an equal basis with others [6]. Rates of disability in Indigenous adults and children are higher than in non-Indigenous Australians. Indigenous adults are 1½ times more likely than non-Indigenous Australians to have a disability or long-term health condition, more than 3 times as likely to have an intellectual disability, and more than twice as likely to require support meeting self-care, communication or mobility needs [7,8]. Similarly, Indigenous children are 30% more likely to require assistance with learning or communicating, have a core activity need for assistance, and a profound or severe disability, than age-matched non-Indigenous children [3]. Up to 27% of Indigenous children in Western Australia (WA) have limitations in vision, hearing, or speech [9]; a statistic likely reflecting Australia having one of the highest rates of otitis media (OM) in the world [10,11]. Other studies have identified lower scores on performance and development in young Indigenous children as compared to non-Indigenous children [12,13].

Despite these disparities, data on prevalence, type, and service access among Indigenous children in Australia is limited, particularly in urban populations [11,14,15]. Only recently has the Australian national census sought information on disability for Indigenous individuals under the age of fifteen [3]. Problems with Indigenous identification, high non-response rates, and different conceptualisations of disability may mask hidden disability and contribute to under-reporting [14,16].

Low service use

In addition to little prevalence data, which precludes discussion of service access in children, it has been reported that few Indigenous people with a disability access services. In 2008–09, only 5% of users of specialised support services were Indigenous [17], indicating that they are not participating in available programs [18]. In New South Wales, which has the largest population of Indigenous people in Australia, and the largest population with severe or profound core activity limitations, rates of service provision to Indigenous people are below the national average [17]. Barriers in accessing support have been attributed to remoteness, social marginalisation, cultural attitudes towards disability, and culturally inappropriate services [19].

Although not directly targeting disability, cost effective quality early interventions, such as pre-school, have been reported to be key points where development indicators can trigger support, potentially making a difference to life-long outcomes [20,21]. In Australia, just 25% of Indigenous children aged 3.5-4.5 attend any formal early childhood services and these children are least likely to have access to high quality pre-school education [22,23].

Consequences of lack of support

This lack of support and therapies in the early years of life can have devastating consequences for the child, their parents/carers, family, and community; contributing to cycles of disadvantage. Investment in the early years through policies that address social determinants of health has potential to reduce social, economic, and health disparities within a generation [2,24]. The need to inform such policies through measuring and understanding the problem and assessing the impact of action has driven this review. Specifically, we aimed to answer the following question: What are the factors impacting on the prevention, recognition, and access to support and management of disability in Indigenous Australian children? To answer this question, we conducted an integrative narrative review to ascertain the state of the science, potential solutions, and gaps in services and research.

Methods

Data collection

We undertook an integrative review which is a method that incorporates disparate sources, methods, and types of literature and facilitates development of comprehensive accounts of phenomena [25] while summarising literature, identifying gaps, and recommending further research in a given area [26]. In contrast to a systematic review, an integrative review, although conducted with systematic methods, discusses and summarizes literature on a particular topic, without generating a pooled summary or focusing on questions of efficacy.

The literature search strategy was designed and conducted in consultation with a health librarian in August 2011. Peer-reviewed literature was identified via searches of Medline, PsychInfo, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Indigenous Australia, Australian Public Affairs Information Service-Aboriginal and Torres Strait Islanders (APAIS-ATSIS), Aboriginal and Torres Strait Islanders Health (ATSIHealth), the Australian Indigenous Health InfoNet, Education Resources Information Center (ERIC), and Cochrane Library databases and the Google Scholar search engine. Database searches were limited to articles written in English and published between 1990 – July 2011. Additional literature was identified via retrieved studies’ reference lists. Literature was included if it 1) centred on Indigenous Australian children or families; 2) centred on issues surrounding Indigenous Australian children with a disability or impairment; and 3) depicted aspects of prevention or recognition of disability or access to support, treatment, or management. Articles were excluded if they did not report separately on Australian Aboriginal and Torres Strait Islander Peoples or did not concern childhood disability. Search terms were Medical Subject Headings (MeSH) terms and keywords including derivations of child, (newborn, baby, babies, infant, infants, children, childhood) and Indigenous (Indigenous, Australian Indigenous, Australian Indigenous, Aborigine, Oceanic ancestry group) and disability (intellectual disability, learning disorder, language disorder, communication disorder, hearing impaired, hearing loss, hearing disorder, visually impaired, mentally disabled, developmental disability, attention deficit, disruptive behavior disorders, child behavior disorders, child development disorders, motor skills disorders, cognition disorder, speech, language disorders, autism, autistic disorder, Aspberger syndrome, physical disability) tailored to relevant databases. For the inclusive purposes of this review, the term disability encompassed developmental delay, intellectual disability, sensory impairment, and physical disability. Theoretical and empirical papers were included and no restrictions were imposed on study design or methodology.

The grey literature was searched using broad terms depicting Indigenous children with disability after identifying websites of relevant government and non-government organizations in Australia, as well as Australian universities and research centres. We contacted key authors to request copies of relevant reports not available via the internet. Additional grey literature was sourced using the databases listed above, the internet search engine Google, and via hand searching of reference lists.

Data evaluation and analysis

Two authors independently reviewed all titles and abstracts for relevance to the review topic. They obtained full copies of retained articles for detailed examination to determine suitability for inclusion. Any disagreement between authors was resolved by a third author. Two authors extracted data from retrieved documents, into a customised data extraction spreadsheet with columns depicting disability focus, methodological and intervention features (if available), aims, key findings, and information pertaining to prevention, recognition, and access to support and management of disability. Strength of findings of primary sources were evaluated via MeInyk and Fineout-Overholt’s Levels of Evidence ranking system [27]. In addition, observational studies were evaluated using the STrengthening the Reporting of OBservational studies in Epidemiology checklist (STROBE) checklist [28], and intervention studies were appraised via the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) checklist for non-randomised health and social interventions [29]. Analysis proceeded with categorisation of data guided by the research question and the Chronic Care framework, which summarizes elements for improving care in health systems at individual, community, practice and organization levels [30].

Results

The literature search resulted in 189 peer-reviewed articles reporting both empirical studies and theoretical articles. Following application of inclusion and exclusion criteria, twenty-seven articles were included in the review (Figure 1). The majority of peer-reviewed articles (n = 20) described otitis media (OM) and hearing loss in Indigenous peoples. With the exception of studies describing national data, just four articles reported data on urban or metropolitan Indigenous populations. Nearly twenty per cent of the articles (n = 6) were over ten years old. The majority of articles reported on descriptive and observational studies (n = 11) (Table 1). STROBE scores ranged from 4 (indicating provision of little detail on which to judge veracity of findings) to 21 (indicating provision of detailed information) [28]. The mean STROBE score was 14.7 out of a possible 22 (67%).

Just four intervention studies were identified and these addressed stigma, sound amplification (management), and screening (recognition) (Table 2). All reported beneficial outcomes, three of which involved teaching strategies and/or hearing support in classrooms with evaluations of literacy, communication, and other educational outcomes. The mean TREND score was 11.9 out of a possible 22 (54%).

Five discussion papers (Table 3) and six literature reviews were identified, yet just one provided a detailed description of the review process (Table 4). Three reviews centred on hearing impairment and OM exclusively (Table 4). We identified six reports from the grey literature (Table 5). Although we endeavoured to ascertain factors impacting on prevention, recognition, and access to support and management of disability, we did not identify articles describing prevention other than a call for collaborative development of health-related promotional material to minimise ear infections [31]. Following this summative account of literature identified, we now provide a narrative summary using the framework of the Chronic Care model’s elements for improving care in health systems at multiple levels.

Individual and community-related factors

Different conceptualisations of disability

Perceptions of Indigenous disability affect recognition and access to support and management. Reports highlighted differing views between Indigenous and non-Indigenous people’s conceptualisations of disability, impairment, and behaviours that may hinder identification, an important step towards early intervention that can improve a child’s social, language, and communication development and contribute to school readiness [32]. For example, Indigenous people with a disability may experience stigma in their communities and for some, independence may not be prioritised [32]. These views may hinder help-seeking behaviours.

While Indigenous families and communities may not perceive a child as having a disability, ‘labelling’ Indigenous people with a disability as ‘the Other’ and as a specialised field is apparent within the mainstream Australian service system [33]. Hence, appreciating these differences in meanings and understandings of disability concepts among both service providers and Indigenous peoples is important to obtaining better understandings of needs, expectations, and preferences.

Although challenges to access are a feature of disability, this is likely aggravated among Indigenous families where disclosure of a problem may lead to unwanted attention on circumstances and social situation [14]. Fear and distrust of organisations, marginalisation, and disadvantage have made some Indigenous people reluctant to access support and services [18]. Many individuals fear that their children will be taken from them [34,35]. Other factors associated with being Indigenous that impact on the experience of disability include the diversity within Indigenous communities, importance of family, community, and culture, social isolation associated with disability, and social disadvantage which alienates some families from service providers [19].

Systems-related recognition factors

Regular hearing screening programmes in schools are essential to detect and prompt appropriate treatment for children [31]. Although screening for hearing loss is important, factors impacting on this taking place in schools include the schools’ awareness of this service, relationships developed between service providers, Indigenous perceptions of hearing loss and disability, funding, staff turnover, training and equipment, health policy, and access to health facilities [31].

Need for culturally appropriate screening instruments and psychometric tools

Culturally appropriate assessments are difficult to achieve as standard intellectual and social assessments have been found to be culturally-biased. D’Aprano et al. [13] found that Indigenous children were well behind non-Indigenous children using the Brigance developmental screening tool. The language, cultural relevance, and its administration method limit its use. This study has highlighted a need to adapt an appropriate instrument to guide developmental surveillance and monitoring in remote Australian Indigenous communities. It has been argued that the criteria developed for the allocation to special schooling may constitute indirect racial discrimination against Indigenous students and there is a need for assessment and evaluation by Indigenous educators of the basis on which Indigenous students are placed in special classes at school [36].

Provider-related factors affecting recognition

Such complexities made professionals reticent to impose labels, in some cases. This can result in an underappreciated level of disability and some Indigenous students not receiving the support they need. It was discussed that if a label can facilitate additional support, a culturally appropriate professional assessment and intervention was warranted, but not otherwise [19].

Cultural training and workforce issues

A significant proportion of literature on hearing loss in children centres on the learning environment and teachers. Cultural considerations in behaviour, language, and conceptual differences are critical in appropriately identifying, assessing, and managing hearing loss and other disability in young Indigenous children at school [37]. Greater access to Indigenous teaching staff and Indigenous Education Workers in schools will facilitate culturally appropriate support for Indigenous students [37,38]. Professional development and cultural competence training for non-Indigenous teachers, including information about hearing loss, effective cross-cultural communication strategies, behaviour management strategies [38], and possible behavioural indicators of Indigenous children’s hearing loss [39] will contribute to Indigenous children’s school experiences as well. Ongoing training of Aboriginal community audiometrists to provide community, school, and preschool (including infants) screening programs are additional ways to address these issues [27].

Barriers to service access

O’Neill [32] reported that factors contributing to Indigenous use or non-use of disability support services are complex, and involve perceptions of attitudes, understandings and values regarding disability, language barriers, poor coordination between services and levels of government, workforce issues, racism among service providers, and socioeconomic disadvantage, including housing and transportation.

Access to services is often limited in remote areas [37]. Gunasekera found that rural and remote areas managed more cases per week than their urban counterparts, but had less access to specialist audiology services [40]. Urban-dwelling does not guarantee timely access to critical services, however. Although 20% of rural/remote Indigenous children wait longer to see audiology services for testing than the guideline recommended 3 months, one in eight Indigenous children nationwide wait longer than recommended for ears, nose and throat services. These results indicate that delays between presentation and treatment may be more widespread than what is generally perceived [40]. Government-funded hearing services, in particular, have been depicted as not meeting the needs of Indigenous people [37].

Potential solutions – ways of working with Indigenous families and children

Involvement of the family in bi-cultural education was suggested as a facilitator of family engagement in primary health prevention and treatment [41]. In regards to working with health and service providers, families preferred to build a relationship over time, opportunities for discussion, and an emphasis on the abilities of the child rather than the disability [19].

Recommendations for mitigating hearing loss in schools include phonological awareness programs and hearing support services which have demonstrated improvements in literacy levels [42,43]. Use of classroom-wide sound field amplification has been found to encourage children’s interaction with teachers and peers [44]. Importantly, amplification may reduce stigma and negative attitudes of peers which have been found to inhibit hearing aide use [45,46]. Although this appears to be a rapid, cost effective part of the solution, there are no clear or enforceable standards for classroom acoustics in Australia [44].

Although not delineating specific disabilities, three articles were identified that centred on developing and maintaining relationships between allied health professionals, young Indigenous children and families, and teachers. Facilitators to successful occupational therapy access included investing and committing time to establish and maintain therapeutic relationships and using appropriate communications strategies such as gaining and giving knowledge with a respectful tone, using understandable language, and demonstrating unfamiliar tasks [47]. Additional facilitators include setting the program in culturally safe and accessible locations, such as an Indigenous health or educational setting, and involving Indigenous health workers [47-49].

Gap in research – the family

Overall, the voices and needs of Indigenous families of children with disabilities were minimally represented in the literature identified. It was noted that teachers’ reports of behavioural issues reflective of unidentified hearing impairment, for example, can impact on the family negatively [37]. One report specifically targeting Indigenous families of children with disabilities indicated that families wanted practical support such as transport to multiple appointments and completing forms.

Discussion

With one of the highest rates of OM in the world, it is not surprising that a preponderance of literature on Australian Indigenous child health depicts the implications of this preventable and treatable disease. Despite disability manifesting in low rates of school participation and recidivism, there are minimal data on Indigenous childhood and disability [50], as has been reported in other Indigenous populations [16]. This was apparent in the current review as well as in a recent analysis of descriptive studies describing the health, development, wellbeing of Indigenous children which found that research predominantly addressed physical health (75.1%), health determinants (27.6%), and mental health and wellbeing (2.8%) [50]. The resurgence in the literature is evident in adolescence where drug, alcohol, and incarceration manifest as evidence of marginalisation, racism, and a failure to address early childhood disabilities, many of which are treatable with early intervention [51].

Despite 53% of the Indigenous population living in major cities or inner regional areas of Australia [52], the literature predominantly focused on rural/remote-dwelling populations [50]. Likewise omitted from the extant knowledge, particularly in peer-reviewed forums, are the experiences of the Indigenous family, carers, and children and their unmet needs. This is an important focus for future research.

Factors impacting prevention, recognition, and access

The higher rate of disability in Indigenous compared to non-Indigenous Australians is a pattern of disparity seen in many Indigenous populations throughout the world[16]. Socioeconomic disadvantage has been linked to intellectual and developmental disability, both as cause and effect, given inequitable resource allocation within social systems and subsequent contextual issues [53]. Socioeconomic disadvantage, racism, and oppression influence learning and health outcomes [16]. The absence of Indigenous Australian child disability statistics until 2006 reflects this history of dispossession, distrust, and enduring disparity. The legacy of stolen generations and a recent resurgence of government control [54] has resulted in a strong scepticism and mistrust of government organisations.

Considerations for addressing disability in Indigenous children are depicted in Figure 2. Differences between Indigenous and non-Indigenous people’s conceptualisations of disability, impairment, and behaviours may impact on identification or diagnosis of a disability, an important step towards early intervention that can improve a child’s social, language, and communication development and contribute to school readiness [16]. As noted in the Australian literature, systematic screening for delay or impairment, particularly where English is not the first language, is vital [16].

Considerations in dealing with disability in Aboriginal children.

The significant and enduring consequences of unaddressed disability were discussed and suggestions for improving awareness of cultural differences in education settings and tailoring programs to address the needs of Indigenous children provided. Johnston [55] has described education as positively associated with health through mediating pathways that exist at individual, family and community level. Johnston [55] urges clinicians to consider early childhood and school education as an important focus that requires rigorous research into interventions that address the barriers to effectiveness in implementing quality educational experiences and opportunities for Indigenous children.

There are a number of strategic initiatives to address the data shortcomings, to date, and to address factors that will maximise Indigenous participation in society. Among these is the Study of Environment on Indigenous Resilience and Child Health (SEARCH) project, a prospective longitudinal cohort study which will be a long-term resource to investigate the causes and trajectories of health and illness in Indigenous children aged 0–17 from urban and large regional centres in New South Wales, Australia, to identify potential targets for interventions to improve health. Data is being collected on OM, hearing impairment, and developmental delay [56]. Another example is the Gudaga study, a prospective descriptive longitudinal cohort study assessing the health, development, and service use of Indigenous infants and their mothers in Southwest Sydney [15]. The work of the Telethon Institute for Child Health Research is also providing a stimulus for addressing the health and well-being of Indigenous children [57].

Strengths and limitations

This review was limited by the available published literature and therefore does not reflect the scope of the problem. Although government reports and other sources of the grey literature were reviewed for this project, sparse data reflects that many issues of childhood disability hover below the radar and only manifest when the consequences are dire and catastrophic [58]. Although a feature of disability [58], this is likely aggravated among Indigenous children where a disclosure of a problem may cast an unwanted focus on family circumstances and social situation.

Given that the needs of these populations are very unique, the outcomes of the retrieved studies may not be generalisable to the entire Australian Indigenous nor other Indigenous populations, necessarily. This review was undertaken using rigorous methods and has identified potential solutions for addressing childhood disability. This review has elucidated important contextual determinants of child health and disparities among Indigenous Australians. It also underscores the importance of shifting from a purely biomedical lens to a holistic approach to address the needs of vulnerable Indigenous children. This will require ongoing partnership and collaboration between health, education, and social service agencies.

Given the diverse study designs and inconsistent reporting, the ability of this review to decipher strength of evidence was limited. Instead, this review has provided a snapshot of the current foci of literature and approaches to describing disability in Australian Indigenous children.

A way forward

The solutions for addressing health disparities and maximising societal participation among Indigenous Australians have been clearly identified by Indigenous people. Recognising and addressing entrenched and institutional racism is an important first step in ensuring the needs of Indigenous children are addressed [59].

This review has indicated that a great deal is still unknown about Indigenous childhood disability, yet important foci should include prevention of problems that improve health and living situations, particularly effective antenatal care. Importantly, factors that promote prevention, recognition, access, and viable solutions, as summarised in Figure 2, are warranted.

Further research must be conducted in order to provide evidence for effective and sustainable practice and policy. This is particularly the case for developing culturally appropriate interventions. Ensuring such research is led by Indigenous people using appropriate methods is a critical step in developing tailored and targeted solutions. It is critical that health and social services are accessible and acceptable to Indigenous people. Indigenous-led and controlled services are an important form of engagement. Increasing the workforce participation of Indigenous people in health, education, and social services [60] is an important step and strongly linked to addressing childhood disability and maximising participation in the education system [38].

Achieving these goals requires addressing entrenched power relationships and dismantling barriers between mainstream and Indigenous controlled services. It also will require challenging traditional professional boundaries and decreasing silos between health, education, and social services. Given the links between childhood disability and education, teachers have an essential role to play in monitoring developmental stages, thus necessitating teacher training that ensures appropriate recognition of potential disability. Greater congruency between health and education systems needs to occur, as well as other strategies to ensure children with hearing disabilities are not left behind, such as amplification systems with classrooms [61].

Conclusions

Despite higher rates of disability than in non-Indigenous children, this review has identified the scant focus on disability in Indigenous children in the face of the burden and ramifications of not achieving educational and social milestones. Given the lack of research in this area, further investigation must be conducted. The emphasis on OM in this review reflects the hard work of a committed group of researchers, but currently, the literature fails to encapsulate the breadth and complexity of Indigenous childhood disability. Although extensive investment is apparent in downstream health problems, ensuring the foundations of health and wellbeing through early intervention is critical in decreasing health inequity.
